Hello. Why would a double-slit experiment for things like bullets being fired from a gun that shoots in random directions produce a probability distribution like those of objects or particles, but the double-slit experiment for an electron gun produce a wave-like interference pattern? I read in another thread that electrons are actually particles that are described via a wave function and that they are not actually waves. But why do they act like waves if they are not waves? If you say they have an undulatory nature, what mechanism gives them this nature and how does it determine in what scenario a particle like an electron will act like a wave?
